Volume of Pyramids, Cones, and Spheres
Ever wonder how much space is inside a pyramid or a ball? Let's break down these volume formulas so you can solve problems easily!
For a rectangular pyramid, the volume equals one-third of the base area times the height: V = ⅓Bh (where B = L×W). If you have a triangular pyramid, the formula is similar, but the base area is calculated differently: V = ⅓Bh (where B = ½b₁b₂).
Cones follow a similar pattern to pyramids. Their volume is one-third of the base area times the height: V = ⅓πr²h. For spheres, the formula is V = ⅘πr³, where r is the radius of the sphere.
💡 Quick Tip: All these formulas include a fraction (⅓ or ⅘) multiplied by the base area or the cube of the radius. Remember that the base area changes depending on the shape!
Let's look at an example: For a triangular pyramid with a base of 9ft by 12ft and height of 10ft, we calculate: V = ⅓(½×9×12)×10 = ⅓(54)×10 = 180ft³
When solving these problems, take it one step at a time - first find the base area, then multiply by height, and finally multiply by the fraction in the formula.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
